NEW YORK DAILY NEWS – One of two 16-year-old girls accused of conspiring to kill students at their suburban Denver high school has been charged as an adult after prosecutors say she bought a BB gun for target practice and mapped plans for an attack.
Prosecutors on Tuesday charged Sienna Johnson with conspiracy to commit murder and asked that she not be allowed to return to Mountain Vista High School in the affluent suburb of Highlands Ranch. Defense attorneys requested a hearing to transfer the case back to juvenile court.
A judge set her bond at $1 million. Prosecutors said Johnson showed no remorse and told investigators that if she were released she would try again and better hide her plans.
The girls were arrested after police were alerted to their plans on Dec. 12 via a text-a-tip program developed for schools.
Prosecutors are awaiting the results of a mental health exam and other evidence before deciding whether to charge the second girl as an adult. She faces another hearing on Jan. 14.
